Problems solved by technology

In addition, most of the existing multi-field coupling test benches focus on the realization of multi-physics environment, and often lack real-time online monitoring / observation of damage. In situ fracture behavior, damage evolution and failure mode of functional materials and structures in a field coupling environment, it is impossible to carry out in situ failure research and life prediction of materials in a real-time coupling environment
